* I picked up this handy tip from al-Qaeda's "Inspire" monthly terrorist training magazine.
https://en.wikipedia.org/wiki/Inspire_(magazine)
The magazine’s aim is to inform and persuade a committed audience by distributing internal communications called “auto-propaganda” to strengthen morale, reduce dissent, or justify and legitimize an attack or controversial doctrine. It was also used to target an uncommitted audience to eventually win sympathy and support. Therefore, AQAP has the ability to represent themselves and their actions exactly as they wish. The controlled message is unfettered from the scrutiny of the local and international media.[9]

Repeat, LOUD and OFTEN.
Just like repeated lies change viewpoint, so does REPEATED truth.
Inspire is a unique terrorist publication in that it is very specific in the audience in which it targets instead of publishing general ideological arguments to all Muslims. Studies in terrorism[32][33] have noted that most Islamic terrorist attacks on the West are perpetrated by well-educated men living in the West, with an average age of 26 years.[32] AQAP also is aware of this, and Inspire magazine targets this demographic.
